Overview of this book

Becoming a solutions architect requires a hands-on approach, and this edition of the Solutions Architect's Handbook brings exactly that. This handbook will teach you how to create robust, scalable, and fault-tolerant solutions and next-generation architecture designs in a cloud environment. It will also help you build effective product strategies for your business and implement them from start to finish. This new edition features additional chapters on disruptive technologies, such as Internet of Things (IoT), quantum computing, data engineering, and machine learning. It also includes updated discussions on cloud-native architecture, blockchain data storage, and mainframe modernization with public cloud. The Solutions Architect's Handbook provides an understanding of solution architecture and how it fits into an agile enterprise environment. It will take you through the journey of solution architecture design by providing detailed knowledge of design pillars, advanced design patterns, anti-patterns, and the cloud-native aspects of modern software design. By the end of this handbook, you'll have learned the techniques needed to create efficient architecture designs that meet your business requirements.

The building blocks of quantum computers

The basic building block of a quantum computer is the qubit. Qubits in QC are similar to bits in classical computing, but they behave very differently. Let's learn more about qubits.

Qubits

Classical bits can hold only a position of 0 or 1, but qubits can hold positions between 0 and 1, and multiple positions at once. Qubits are quantum systems that scientists and engineers can control. Some examples of qubits are atoms, molecules, and photons.

Quantum states are represented by the little flags "", called Dirac notation. A single classical bit is denoted by 0 or 1, while a single quantum bit (qubit) is denoted by complex linear combinations of and . Qubits are two-dimensional vectors with complex coefficients, as shown below:
